“…In order to validate present experimental results, the base temperature (T b ) of the heat sink obtained from the present experimental study is compared with the test data of Arshad et al, 21 Mahmoud et al, 37 Tauseef-ur-Rehman and Ali, 55,59,60 and Tauseef-ur-Rehman et al 58 ( Figure 9A, B). Most of the studies consider heat sink having dimension of 100 × 100 × 25 mm 3,55,[58][59][60][61][62] (56 C-58 C) 21,58,59 for the analysis.

Present paper reports the thermal performance of various phase change material (PCM)-based heat sinks during melting process for cooling of portable electronic devices through experimental investigations. Heat sink configurations include unfinned with pure PCM, finned with pure PCM, unfinned with metallic foam (MF)-PCM composite, and finned with MF-PCM composite. Paraffin wax is used as PCM, and tests have been carried out for various input heat flux values (1.3, 2.0, and 2.7 kW/m 2) at different volume fractions of PCM (0, 0.50, 0.86, and 1). The effect of various parameters such as PCM volume fraction, heat sink type, and heat flux on the stretching of operating time to achieve a set point temperature (SPT) is studied. Results obtained from the current experimental investigation are compared with the existing test results. Also, unfinned heat sink without and with PCM is used for baseline comparison. The evolution and propagation of melt front inside the heat sink are studied through photographic observation. The enhancement in operating time is found to vary with the SPT and heat flux values. MF-PCM-based heat sinks are more advantageous for higher value of input heat flux (2.0 and 2.7 kW/m 2). For q 00 = 1.3 and 2.0 kW/m 2 , four-finned MF-PCM-based heat sink exhibits better performance; while three-finned MF-PCM-based heat sink shows best performance at q 00 = 2.7 kW/m 2. The highest enhancement ratio of 2.97 is obtained at 1.3 and 2.7 kW/m 2 for four-finned MF-PCM heat sink and three-finned MF-PCM heat sink, respectively. Also, threefinned heat sink provides higher heat transfer rate and highest thermal conductance at q 00 = 2.7 kW/m 2.

Cold energy storage devices are widely used for coping with the mismatch between thermal energy production and demand. These devices can store cold thermal energy and return it when required. Besides the countless advantages of these devices, their freezing rate is sluggish, therefore researchers are continuously searching for techniques to improve their operating speed. This paper tries to address this problem by simultaneously combining a network of plate fins and various types of carbon-based nanomaterials (NMs) in a series of complex computational fluid dynamics (CFD) simulations that are validated by published experimental results. Horizontal, vertical, and the combination of these two plate-fin arrangements are tested and compared to the base model. Subsequently, several carbon-based NMs, including SWCNT, MWCNT, and graphene-oxide NMs are utilized to further improve the process. The influence of these fin networks, nanoparticle types, and their volume- and mass-based concentrations within the PCM container are studied and discussed. According to the results, carbon-based NMs exhibit superior performance compared to metal-oxide NMs, so that at identical NM volume and mass fractions, MWCNT particles present a 2.77% and 17.72% faster freezing rate than the CuO particles. The combination of plate-fin network and MWCNT particles is a promising technique that can expedite the ice formation rate by up to 70.14%.

“…In these circumstances, the combination of active-passive systems, for example, the electric systems combined with heat storage systems, has provided sustainable outcomes. Further, in heat storage systems, latent heat storage/release technology is supposed to be competitive due to relatively stable operating temperature and high heat storage density enabled by phase change materials (PCMs) (Huang et al, 2021). PCMs are the core components by which various latent heat-based heat exchangers (LHEs) can be configured and equipped with electric-driven thermal management systems of buildings.…”
